SEPARABLE BOOK.

SPECIFICATION forming part of Letters Patent No. 584,997, dated June 22,1897.

Application iiled November 2 7, l 8 96 To @ZZ whom it may concern:

Be it known that I, FRANKLIN H. GILsoN, of Wellesley, in the county ofNorfolk and State of Massachusetts, have invented certain new and usefulImprovements in Separable Books, of which the following is aspeciiication.

This invention relates to an album or other book comprising a series ofleaves and a cover separably connected thereto.

The invention has for its objectto .provide an improved construction ofthe leaves and cover of an article of this character, whereby the samemay be readily assembled and separated and a collection of any desirednumber of leaves may be used with the same cover, the cover beingextensible, so as to lit a collection of leaves of any desiredthickness.

The invention also has for its object to provide an improved detachablecover or temporary binder for other purposes, such as holding sheets orcards having samples of cloth and other materials. y

The invention consists in the improvements which I will now proceed todescribe and claim.

Of the accompanying drawings, forming a part of this specication, Figurel represents a perspective view of my improved album, showing the backlid partially removed. Fig. 2 represents a perspective view of a portionof the album, showing the back lid in place. Fig. 3 represents aperspective view of a portion of the album, the front lid beinguppermost. Fig. 4 represents a section on line 4 4 of Fig. 2. Fig. 5represents a sectionsimilar to Fig. LL, showing a greater number ofleaves. Fig. 6 represents a perspective View of a portion of one oftheleaves. Y

In the drawings, a represents the front lid, and b the back lid, of myimproved albumcover. These parts may be of any suitable constructionandmade of any suitable material. c c represent a series of leaves whichare interposed between the lids 0. and b and are connected thereto bythe means hereinwith a exible extension a', formed to extend over theback of the series of leaves c and to project between the last leaf ofthe series and the back lid b.

. sentire. 613,673. cromati The front lid a is provided near its innerend with orifices d d, while the back lid b is provided near its innerend with corresponding orifices d d', which are'arranged to coin- 55cide with the orifices d d when the lids are in place at opposite sidesof the series of leaves.

The extension a' is provided with longitudinal slots e. e, which arearranged to coincide with the oriiices d d d d', so that a cord f 6o maypass directly from each orifice d to the corresponding orifice d througha slot e.

Each leaf c has near its inner end a slot c', said slots extendinginwardly in opposite directions from the top and bottom edges of theleaves. rIhe slots c are arranged so that their inner ends coincide withthe orifices d d CZ d when the several parts are assembled. I prefer tomake each leaf of a main portion 2 of comparatively stiff and heavycardboard, an end portion 3, of similar material, composing the innerend of the leaf, and a thinner flexible portion 4, preferably made ofone or more layers of cloth, connecting the portions 2 and 3.

In assembling the above-described parts I place the series of leaves onthe cover a, fold the extension c. over upon the series of leaves, asindicated in Fig. l, and pass the cord f first through one of theorifices d' in the back lid, the corresponding slots e and c', and thecorresponding orifice drin the cover a, then along the outer side of thecover a, as indicated in Fig. 3, through the other orifice CZ, the slotsc in the opposite edges of the leaves, the other slot e in the extensiona', and the other orifice d' in the back lid b, after which I tietogether the freev ends of the cord on the back cover b, as indicated inFig. 2.

It will be seen by reference to Figs. 4: and 5 that the slots e in theback extension a enable the cord f to pass through said back extensionat various points, so that the cover can be accommodated to any desirednumber of leaves c, the number shown in Fig. 5 being considerablygreater than that shown in Fig. 4.. It will also be seen that the slotsc in the leaves c enable the leaves to be readily inserted and removedfrom any part of the pack by loosening the cord and slipping it out ofslots c.

I am aware that it is not new to provide ICO slots in the leaves of analbum or book and to secure the same by cords, and I do not thereforeclaim this feature broadly. I am also aware that a cover composed of afront and a back lid, one having a flexible eXtension to serve as theback of the cover, so that the same cover can be used with an interposedpack of leaves of any desired thickness, is not broadly new. I am thefirst, however, so far as I ain aware, to provide the two lids withcoinciding orifices and the back extension with longitudinal slotsintersecting said orifices and to employ a cover of this constructionwith a series of slotted leaves.

My invention is not limited to photographalbums, but may be embodied ina separable book of any other nature, such as a samplebook for holdingsamples of cloth and other merchandise.

I claiml. Abook or album cover comprising a front lid provided withorifices near its inner end; a flexible extension or back formedthereon, and provided with longitudinal slots arranged to register withsaid orifices; and a back lid having orifices near its inner endarranged to register with the said slots and first-mentioned orifices,said slots and orifices being arranged to receive a cord or lacing,whereby the lids may be connected with each other and with a series ofleaves interposed between the lids, the slots permitting said cord topass through the flexible extension at various points, as set forth.

2. A book of the character specified, coniprising two separable lids,each having orific-es near its inner end; a flexible extension or backformed on one of' said lids, and provided with longitudinal slotsarranged to register with the orifices in the lids; a series ofindependent leaves interposed between the lids, and having slotsextending inwardly from their edges near their inner ends, the innerends of said slots coinciding with the orifices in the lids; and alacing-cord connecting said lids and leaves, the said cord passingthrough the orifices of the lids, the slots of the back extension, andthe slots of the leaves.

In testimony whereof I have signed my naine to this specification, inthe presence of two subscribing witnesses, this 20th day of November, A.D. 1896.
